My mastery page is never what i actually chose?

My mastery page is never what i actually chose?

Every time i play a game and select a mastery page for some reason it decides to choose a different page? Anyone else having this problem? It's really starting to screw me over and i'm not sure why it's happening

Can you think of anything in particular that you did that may have caused this? Any habits in how you set your masteries, anything?

A similar thing that happens to me is when I edit my mastery page it doesn't automatically select that page anymore; I have to manually change it. This caused me to frequently select the wrong page (been happening since mastery page rework). I have gotten the hang of it by now, but it was terrible when it first started.

Hey, I've had this happen once or twice, but it hasn't been in a patch or two. I'll give what info I can, to see if it can help. It seems inconsistent with what brings it on, but every time it HAS happened has been:

1. On my second game after launching the client.
2. First game, I select the Mastery page without using the edit button at all.
3. Second game, I select a different Mastery page without using the edit button at all.

I've tried replicating this, and it looks like there's another factor to it I can't pinpoint, because just following these steps doesn't do it. I do know that these are common to each time I've had it happen, but they are not the only things defining it.

I've experienced this, and I believe I have a temporary fix until Riot figures out what's happening:

After deciding which mastery page you want to use, click to edit your masteries. Take a point away on the page you want to use, click save and use, then put the point back. You should now be using the correct page.
